Homemade TT 5.0 and emissions test: PASSED
Surprise surprise-she passed. Not by much tho
Hydrocarbons: state std=220 ppm; TT notch=219 ppm
CO: state std= 1.2 PCT; TT notch=0 PCT
Here in MD they put the car on a dyno and put a load on it and run thru various rpms, braking etc.
Except that this was originally a 4 cyl car the car is very stock for a V8 (other than the turbo setup).
This car ir running all of its original pollution equipment except that the cats are aftermarket. It has its original 19# fuel injectors but it is running two fuel pumps. Mass air meter, throttle body etc are stock.
I was worried that the dyno would load up the car and start spooling the turbos which would dump fuel via the fmu. I had the timing set a little retarded-which is basically how I would run it anyway. I was using the computer controlled timing.
The car went on the dyno and I was watching the fp gauge on the hood to see if he would spike it. Seemed ok going thru the gears. But then, a yellow screen came up that said "Vehicle Speed Excursion-Test aborted" After that, he cleared the machine and sat the car at 2500 rpm for like 90 sec and then dropped it to idle. The car had been sitting around idling for like 45 minutes. So the test was actually some kind of idle test not the real dyno test.
What does it indicate if your hc is high and CO is low in that kind of test?
Bottom line tho: PASSED Gotta throw back a few pints to celebrate that one.
Now on to my 42# injectors, adjustable fp regulator and proM maf and dump the fmu. I would not mind seeing how that does on emissions. It actually could do better once I get everything dialed in on the dyno.
